IMPROVEMENT IN CAR-COUPLINGS.

Specification forming part of Letters Patent No. 208,336, datedSeptember 24, 1878 application filed May 15, 1878.

To all whom it may concern:

Be it known that I, JOHN D. Ross, of Macon, in the county of Bibb andState of Georgia, have invented certain new and useful Improvements inCar-Couplings; and I do hereby declare that the following is a full,clear, and exact description thereof, which will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to letters of referencemarked thereon, which form a part of this specification, and in whichFigure 1 represents a vertical longitudinal section of my completeinvention; Fig. 2, a front elevation of the same; and Fig. 3, aperspective view of the coupling-link;

Similar letters of reference occurring on the several figures indicatecorresponding parts.

My invention relates to improvements in car-couplings, and is designedas an improvement upon Letters Patent N 0. 190,984, granted to me underdate of May 22,1877 and it consists of a draw-head provided with apivoted plate adapted for operation in connection with a coupling-linkof peculiar construction, all as will be hereinafter more fullydescribed, and pointed out in the claim.

Referring to the drawings, A A represent the two draw-heads, similar inconstruction, and provided with bars 13 B for attaching the same to theplatforms of cars. The opening in the face of the draw-heads for theintroduction of the coupling-link is formed by the inwardly-inclinedsides and bottom 0 C and D and pivoted top plate E, projectingdownwardly and resting on flanges cut in the side walls C 0, so as toleave an opening at the rear of the inclined recess, as shown in Figs. 1and 2, said plate E being pivoted at its upper part by lugs on each sidefitting into corresponding recesses in the side walls 0 O, and having abeveled edge, a, at its bottom.

G represents the coupling-link, having an open arrow-shaped head, I), atone end, and an opening, 0, at the opposite end, as fully shown in Fig.3.

The draw-heads A A are each provided, in

the rear of the opening F, with upper and lower cross-bars, H H, havinga central openin g for the introduction of the coupling-pin I.

.The construction of my invention being as described, it will beobserved that the drawheads A A can be used in connection with eachother, as well as with other forms of draw-heads now in common use,thereby enabling my improvement to be used on railroads having differentkinds of draw-heads without necessitating any change. It will also beobserved in the operation of my invention that the coupling-link G isfirst secured in one of my improved draw-heads, or in one of theordinary form, by the couplingpin 1, leaving the arrow-shaped end 1)projectin g, which, when the draw-heads come in contact, enters theopening F in the opposite draw-head, and lifts the pivoted plate E untilthe head 1) passes entirely through, when the said plate drops down, andthe beveled bot tom a catches behind the head b, and thereby connectsthe two draw-heads.

The advantages of my invention will be readily apparent without a moreminute description, inasmuch as it combines in its construction andoperation a high degree of simplicity and efficiency with a readyadaptation to the purpose contemplated.

Having thus described my invention, what I claim as new and useful is-In a car-coupling, the draw-heads A A,

having inwardly-inclined sides 0 O and bottom D and upper pivotedgravitating plate E, forming opening F, cross-frames H H, andcoupling-pin I, in combination with the coupling-link G, havingarrow-shaped end or head I) and open end 0, substantially as and for thepurpose specified.

In testimony that I claim the foregoing as my own invention I affix mysignature in presence of two witnesses.

JOHN D. ROSS.
